Log message:
Remove use of sudo from pkg READMEs in a few ports as packages and their
instructions are meant to work on a fresh install.
- easy cases: replace some '$ sudo somecommand' with '# somecommand'
(while there I've swapped some "${RCDIR}/foo start" with "rcctl foo start").
- replace some 'sudo -u user somecommand foo bar' with
'su -s /bin/sh user "/path/to/somecommand foo bar"' and similar.
Not pretty with the -s, but many of the uids that need to run
these commands have /sbin/nologin as their usual shell.
